this should be applied:
http://permalink.gmane.org/gmane.linux.kernel.wireless.general/84311

and you'll probably also need to apply
http://permalink.gmane.org/gmane.linux.kernel.wireless.general/84312

if you want your device to be able to connect :)

(haven't tested these patches with the latest kernel yet, though)
